Maintenance methods of screen printing machine

 The impact during the maintenance and operation of the screen printing machine. Reducing the speed of the machine is another important condition to reduce the moment of inertia of the machine. The detection of the machine preparation state. How is the machine ready. The lower the speed of the machine, the smaller its moment of inertia, so the machine should not always be running at high speed. The smaller the impact during the operation of the machine, the better the printing, and the longer the service life of the machine. It is an important condition to reduce the printing pressure (in a broad sense) to ensure the smooth operation of the machine. It can be detected by inching or turning. If tools and other items are stuck in the machine; if the plate is installed properly, it may damage the plate or make it very difficult to find the rules; if the rubber blanket is installed properly, it may cause printing failure, and in serious cases, it may damage the rubber blanket or the machine. Strengthen the maintenance of machines. Therefore, it is necessary to improve the structure which is conducive to the maintenance of the machine without affecting the normal operation. However, due to the complexity of the printing press, technical reform was carried out. It is obviously impossible to take every factor into account, and the environment will change, so will the content of self-cultivation of machines. Machine maintenance requires that the convenience of machine maintenance should be fully considered in the design of the machine. The quality of the work directly determines the accuracy of the cooperation between the moving parts, and strengthens the self-care of the important parts. Spring is the most important part of the machine used in force balancing mechanism. Spring must have sensitive elasticity, and anelasticity and irrecoverable plastic deformation are very favorable for spring work. Gears, cams, sprockets, rollers and bearings are the most important parts of the press, and their maintenance is different from other parts, because the change of its precision will affect the final printing quality. If the above problems are found, replace the spring immediately. Establish rules and regulations for the maintenance of machines. Such as regular oil change, filter cleaning and regular detection of machine accuracy. The maintenance of offset press should be based on the instructions of the machine. The static maintenance of printing machine refers to the maintenance of the machine under the static state. Screen printing machine

1、 The static maintenance of printing machine and the dynamic maintenance of printing machine。

At the same time, the dynamic operation of the machine can in turn detect the level of static maintenance of the machine。 The following from several aspects to analyze the main content of the machine dynamic maintenance。

1. The dynamic maintenance of printing machine refers to the maintenance of the machine when the printing machine is in a dynamic state. The dynamic maintenance of machines is very important. The static maintenance of machines is the premise of the dynamic maintenance of machines. It is better to oil and lubricate the idling machine first,

2。 Lubrication status of the machine。 So before doing this。 This is also a top priority before going to work every day。 Although the oil leakage of the machine is very easy to observe, it is very difficult to find the cause。 First of all, observe whether the oil circuit of the machine is smooth through the oil indicator。 If there is no oil in the oil indicator or the oil indicator is not clear, stop the machine in an emergency to check whether there is oil leakage in the oil circuit。 For machines with sliding bearings and the like, low speed is conducive to their lubrication, especially inching or low-speed operation has a greater impact on their lubrication。

The oil pump of some machines is driven by the main engine, so when the reverse point occurs, the oil circuit not only cannot be refueled, but will suck the oil of the oil circuit back to the oil tank, which is very dangerous, so the reverse point should be prevented. The lubrication of some important parts can also be detected by the metal temperature near them. If the temperature is too high, it indicates that there is a problem with lubrication. The above aspects are only part of the daily maintenance of the printing press. It directly affects the service life of the printing machine and the quality of the products, so it can not be taken lightly.
